MECHANICAL TOY.

Application. filed April 13, 1925. Serial No. 22,916.

To all whom it away concern:

Be it known that I, Lns'rnn S. GUNDER- MAN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and; useful'ln'iprovements in Mechanical Toys, of which the fol lowing is a specification.

This invention relates to an improvement in toys of the loop type.

The ob'ect of the improvement being to provide a. mechanical toy in which a miniature car or the like is elevated and then run by force of gravity along a. track through a loop and then turned over and received on an opposite track and is retl' rned by again .beingelevated and gravitating along the track through the loop and is again turned over and received on the track in its initial position.

In the accompanying drawing:

Fig. 1 is atop .or plan view of the toy with the car removed.

Fig. 2 is a side view of the construction and shows the car in one position.

Fig. 3 is an end view of the tripping means, for overturning the car.

The device in the form here illustrated comprises a base 5 which is preferably in the form of a shallow rectangular tray, having a pairof uprights 6 mounted thereon, and preferably made from one piece of metal. Supported in the two uprights is a transverse shaft 7. Pivoted on the shaft is a bracket 8. The pivot support being in the center thereof. Supported on the ends of the bracket 8 is a pair of loops 9. The uper extended ends of the loops 9 are formed into hook shaped ends 10. By referring to the drawing it may be seen that the ends 10 of the loops are bent downward and then curved upward forming, hooks 10, for turning over the miniature car or the like, hereinafter described.

The opposite ends of the loops 9 are provided with tracks or runways 11, which have their ends slightly curved upward, and then downward sloping ends 12, terminating in sharply upward extended ends 13.v The downward sloping ends 12 and the upward extended ends 13 form a pocket for receiving the miniature car after being overturned. The sloping ends 13 retaining the car in position until it is sufficiently elevated to gravitate along the track and around the circular loop portion 9.

The momentum of the car being suliicient that when the front end is received and held by the hook portions 10 the rear of the car will turn over and alight on the lower end track sections 12.

Attached to the underside of the loops 9 are brace members 1 1 which extend under the tracks 11 and are secured thereon the supporting members 11 hold the track ends together making a rigid construction.

The loops 9 being an integral of the tracks 11.

Depending from the bracket 8 and mount ed thereon is an arm 15 which carries a pivot'pin 16 at the lower end thereof. A connecting bar 17 has one end pivotally mounted on the pin 16. Mounted on the base 5 is a. spring motor 18 which may be of any suitable type, and secured to the motor is a crank arm 19, having at one end thereof a pivot pin 20, which is pivotally connected to one end of the bar 17. The car 21 forming a part of this toy may be of any approved design, and is provided with a short flange 22-011 each side of the car.

which flanges extend out between the wheels. The flange sections strike the hood ends 10 when the toy is in motion swinging the front wheels of the car out of the hooks allowing the car to make a complete turnover and alight on the track section 12. The car when alighting will be right side up.

The operation of the toy may now be described. Assuming the car 21 is on the track section 12 in the low end of the track, the motor rotates the crank arm 19 driving the connecting bar 17 in a direction as to cause the depending arm 15 to swing on the transverse shaft elevating the track end 12 the car 21 will descend the track 11, around the loop 9 and be caught and overturned by the hooks 10 and received in the track section 12 to' again be elevated on the opposite end ofthe track. The end of the track being alternately elevated during the operation of the toy.

It will be understood that minor changes involving omissions, substitutions, alterations, and changes in the structure may be made without departing from the scope of my invention which is best defined in the following claims.

I claim 1. A toy comprising a pair of tracks, a loop on one end of each track said loops being on reverse ends of said tracks, a bracket connecting said loops and pivotally supported therebetween, means for swinging the track to alternately elevate the ends, and an object adapted to travel in the tracks and loops by gravity, the arrangement being such that: the swinging motion of the tracks in one direction serves to elevate said object to a higher level. from whence it rolls to the opposite end of the tracks, the swing motion in a reverse direction serves to return the object along the opposite track to its initial posit-i on.

2. ll toy comprising a pair of tracks having a loop on one end of each track, said loopsbeing on reverse ends of said tracks, a bracket connecting said loops and pivot-ally supported thez between, means for positively swinging the tracks to alternately elevate the ends and an object adapted to travel on the tracl said tracks being so arranged that the object may be raised at one end of one track from whence it gravitates to the end of the opposite track, the swinging of the tracks in a reverse direction serves to return the object to its initial position.

3. A. toy comprising a. pair of tracks having a loop on one end of each track, said loops being on reverse ends of said tracks, said tracks having reverse incline surfaces, said loops being pivotally supported therebetween, means for swinging the tracks to elevate the ends and a rolling object adapted to travel on -..i.d tracks by gravity and to be transferred from one track to the other by the swinging motion thereof.

A toy comprising a pair of tracks, a loop on one end of each track, said loops be ing integral with said tracks, the said tracks being in a reverse position to each other, a pocket at the lower extended end of each track, the said tracks arr-an (l to swing upward and downward, an object adapted to travel on the said tracks and be received in said pockets and be retained until elevated inging motion of the tracks. T. to comprising a pair of tracks, a cup on each track on the opposite ends thereof, a bracket connecting the said loops and pivotally supported therebetween, the tracks being arranged side by side with re-- verse incline surfaces, one end of each track JitPllClll'lQ underneath the opposite end of another track, and power driven means for continuously swinging the tracks during the operation of the toy and a rolling object adapted to travel on the tracks by gravity and be transferred from one track to the other by the swinging motion thereof.

6. A toy comprising a pair of tracks having a loop on one end of each track, said loops being on reverse ends of said tracks, a bracket connecting said loops and pivotally supported therebetween, a pair of hooks at each end of the said loops, a pocket at each end of said tracks, means for swinging the tracks, and a traveling object arranged to roll on said tracks and be turned over at each end of said loops by the said hooks and be received in said pockets by the swinging of said tracks including means for swinging said tracks to alternately elevate the ends thereof and an object to roll in said tracks by gravity. D g

r. A. toy comprising a base or supporting member, a pair of uprights on said supporting member, a. pair of tracks having rcversely inclined surfaces arranged side by side. a loop mounted on one reverse end of each track, the said tracks and loops being pivotally mounted on the said upright, a pair of hooks on one end of the said loops, arranged to overturn a rolling object adapted to travel on the said tracks, the opposite ends of the. said track being arranged to receive the said rolling object, including operating means supported on the said base, means on the supporting bracket, cooperating vith the said operating means, said op erating means being arranged to alternately elevate the tracks, and an object arranged to roll on the said tracks and be transferred from one track to the other track by the ole vating motion thereof.

8. A toy comprising abase or supporting member, a. pair of upright-s on said supporting member, a pair of tracks arranged side by side, a loop mounted on the reverse end of each track, a b acket connecting the said loops and pivotally mounted therobetween, on the said uprights a pair of books on one end of the said loops arranged to turn over a. rolling object adapted to travel on the said tracks, a pocket on each end of the said tract-ts and extending underneath and slightly beyond the said hooked ends. said pockets arranged to receive the said rolling object after being turned over. an arm depending froin the said bracket and connected thereith, o iierating means supported on the said base, -0l)(!l'fll?lll1' with the said depending arm and a connecting rod to swing the tracl; to elevate the ends and an object arranged to roll on the tracks and be transferred from one end of one track to the end of the opposite track by the elevating motion thereof.
